ABSTRACT:
In conjunction with an operation of flying a plurality of parallel paths in a predetermined pattern utilizing an electronic positioning apparatus including a radar for periodically measuring the distance of the apparatus from each of two spaced apart reference stations and for continuously computing the distance of the apparatus along any of the parallel paths, a method of returning to a last point in a path of the pattern after temporary discontinuance of the operation including resetting an original reference coordinate system so that the zero point thereof coincides with the last point and providing a distance indicator which indicates distance along an axis of the coordinate system so that the pilot can use the indicator to fly the airplane back to zero in the coordinate system.
